have invented new and useful Improvements in Boats, of fication. j V V This invention relates "to improvements in an attachment for light water craft, such as boats, andhas for its primary object to provide the same with out-riggers to prevent the upsetting of the craft.

which the following is a speci- A further object of the invention is to.

provide a boat with means whereby a buoyant floating member may be held'connected to the sides thereof and oifset therefrom to prevent theupsetting or tilting of the boat.

. A further object of the invention is to pro Other objects and advantages will present themselves as thenature of the lnvention is better understood, reference being had to the accompanying drawings in which there is illustrated a simple and satisfactory embodiment of the improvement reduced to prac tice. I

In the drawings: Figure 1 is a top plan view V I ofa boat provided with the improvement.

Fig. 2 is an end elevation thereof showing the buoys partially extended.

Fig. 3 is asimilar view showing the buoys entirely extended.

Fig. 4 is an enlarged detail view of arm joint.

Fig. 5 is a" similar view of another joint.

Fig. 6 is a top plan view, parts being in section, and illustrating a modification.

Referring now to the drawings in detail, the numeral 1 indicates a boat. To the sides 2 and 3 thereof are arranged-buoys or out riggers 4c and 5. These buoys at and 5 are connected to the boat by arms 6 and 7. The arms 6 and 7 consist of members 8, 9 and 10 which are pivotally connected one to the other. The joints 11 and 12 between the said members have their opposing faces serrated as at 13 and 14, while a set screw 15 is employed for retaining the members 9 in fixed alinement or at any desired angle relative to the members 8. The elbow joints l6 and17 are arranged so that they may be operated the 54,063, filed" sateen; 2's, i915. so, 1920. Seria1N o.3 60,074.

and 1 9' prevent a downward operation after a desired vertical position is reached to allow an upward pivotal movement. Thu' iit will be seen that'when the screws 15 are set with the buoys 4 and 5 extended the arms 6 and 7 i being also extended will be held perfectly rigld and the action of the said buoys on the. water" will prevent the boat from being upset a In Fig. 6 the constructioniis substantially similar to that descr'ibed,'b'ut the buoys. 20 and 21 are in the nature-ofair-tight cylinirhi; amass filed Febrii'ary only in an upward direction, while stopsl ls i Be it known that I, QBIN A. KArJrrMAn,

a citizen of theUnite'd States, residlng atders which will add to the buoyanc" thereof and to the buoyancyof the boat. embers 22 connect the arms 6 and '7' at thejoints l6 and -17" whereby the buoys20 and 21 may be "moved'toward or away from, the sides of the boat by a single operator. The

.members22' may be either rigid or flexible,

as desired.

In the remaining figures. of the drawing the boat has on its opposite'sides horizons tally disposed brackets 23 which are round in plan and which are provided with spaced apertures 24:. One arm 25 has its inner rounded head portion 26 disposed over each of the brackets The head portion 26 of the arms 25 is round and provided with spaced apertures27 as well as with a'ce'ntral aperture '28. This last mentioned aperture aline's with a similar aperture in the bracket ends of the arms 25 are pivotally connected,

23. Passing through' the aperturesf28. and the referred to central apertures 'in the' as at 30, to buoyant out-riggers 31. Preferably connected to the sides of the boat by flexible elements are pins 32 disposed ad jace'nt each of the brackets 23, and these pins are designed to be passed through certain of the registering apertures 24 and 27 in the brackets and in the arms so that the buoys 31 may be swung laterally with respect to the sidesof the boat 33 to bring the said buoys close to or a determined distance away from the sides of the boat. 7

Having thus described the. invention,wha

is claimed asnew, is 1 a I 1. In combination with a boat havlng'a buoy arranged at each side thereof, of means securing the buoys to the sides of the boat andpermitting an adjustment of thebuoys with respect to the sides -of' the said boat, including arms connected by an elbow joint,

the outer series of said arms being rigidly connected to the respectivebuoysxand the inner series being pivotally connected to the buoy arranged at' each side thereof; of

sides of the boat, and means associated with a said pivots for retaining the inner series of arms at a vertical inclination or in longitudinal alinement with the outer series of arms."

2; In combination with a boat having a buoy to each side thereof; of means for connecting the buoys to the sides. of the boat and for permitting an adjustment of the buoys with respect to the said sides of the boat includin sectional arms havin elbow oints connecting the same, and the outer sections of arms being secured to the buoys,

brackets on the sides of theboat to which the inner sections of the arms are pivoted,

and means between the pivots and the brackets for permitting and for sustaining the inner arm sections at varying inclinations withr'espect'to the boat. l

3. In combination w th'a boat having a buoy arranged at each side thereof, a pair of spaced arms connecting each buoy to the boat, means whereby the arms may be ar ranged angularly with respect to each other and withrespect to the boat, means for sustaming the arms in such position, and said means including contacting elements at the pivotal connection of the arm sections.

4. In combination with a boat having a means for connecting the buoys to the sides of the boat, including a pair of spaced apart arms rigidly connected to the buoys and pivotally connected to the sides of the boat, each of said arms comprising a pair of pivotally connected sections, means between the inner arm sections and the boat for arranging and for sustaining the said sections angularly with respect, to the boat, and means at the pivotal connection of the sectional arms forholding the outer arm sections and the buoys at predetermined distances from the sides of the boat when the inner arm sections are swung to the referred to angle position on the boat.

5. In combination with aboat having a buoy at each side thereof; of means for con necting and adjusting the buoys with respect to the boat, including apairofspaced armson each side of the boat between'the buoys and boat, each ofsaid arms compris-H ing outer sections which are connected to the buoys, and inner sections, an elbow joint connecting the arm sections, stop members on the confronting faces at the pivotal con nection of the arms, brackets secured to the sides of the boat having outer serrated faces, the ends of the inner arm sections having inner serrated faces that engage 1th the serrated faces of the brackets, and binding 76 nection of the arms, bracketssecured to the sides of the boat having outer serrated faces,

the ends of the inner arm sections havinginner serrated faces that engage with the serrated faces of the brackets, and binding means between the said inner arm sections and the brackets, and operating means for adjusting the buoys with respect to the boat.

when the last mentioned means has been re leased, arranged betweenthe pairs'of arms and connected with the pivots for. the sections thereof. V 1
